IMPROVEMENT IN PENDULUMS.

Specification forming part of Letters Patent No. 173,410, dated February 15, 1876; application tiled January 19, 1876.

To all whom 'it may concern:

Beit known that I, RAYMOND LoNGIN, of Bordeaux, France, have invented a new and useful Improvement in Pendulums, of which the following is a specification:

The object of my invention is to obviate the inconveniences existing in machinery depending upon the use of pendulums, consequent upon the requirement of much gearing for its regulation, by much diminishing, or entirely dispensing with, such gearing; and my invention relates tosuperposing a weight, which takes the place of the ordinary pendulum, upon steel springs, the elasticity ot' which permits and assists in the oscillations necessary t'or an escapement.

In the drawings, Figure I is a side viewr of a machine embodying my principle, and Fig. II is an end view with the weight and springs removed.

A is a circular toothed wheel, forming the escapem'ent to the oscillations ot' the balancependulum fixed on the rod I I. B B are the pillars supporting the axis of the wheel, and secured to'the base G. O C are the fulcrums of the steel blades DD. D D are the escapementsprings, moving from the right to the left, and vice versa, when the spring of the barrel-arbor T is wound up by a crank or key adapted to the square point I. E E are escapement-points xed to the springs D D. F is a cross-piece, which may be of iron, lead, or any other material affording the requisite weight, and unites the ends of the escape ment-springs D D, where its weight permits the springs to make pendulum oscillations. G is the base, to which are screwed the pillars or fulcrums D DB B, and which may vary H is the pivot-rod, riv- Tis a rein forni and matter. eted or soldered to the wheel A.

montoir-box, perforated in its length, and

bearing upon it, next to the post B, a ratchetwheel, M, which, in connection with a springpawl, permits the spring L to be wound while so holding it. In this box the rod H turns freely, as indicatedby the dotted lilies in the drawing. 'l is the barrel inclosing the inotive-spring L, which is rolled in and hooked to the box I.

In operation, when the motive-spring L is .wound up`it is only necessary to swing the with a superposed weight, I may use one or several.

Now, having described my invention, what I claim is-K To form an escapement, the superposed Weight F, in combination with one or more springs, D, arranged to operate in the manner and for the purpose shown and described.
